Hi,
What is the correct way to activate the air con.
Is it to press the "EC" button and turn the temp dials to blue?

As I don't have the manual yet, I'm not totally sure.

Also I've got heated seats, the button has two settings, If I press it up, one LED lights, If I press it down 2 LED's light up on the switch.
Is this for extra heat, or does it mean that the rear seats are heated too?

Cheers

Climate control

I don't know much about the S280, as they were never sold in North America, but I imagine the climate control is automatic like in my 560SEL. In most cars, selecting EC will turn off the airconditioning, as EC is economy mode, and the use of air conditioning can hurt your fuel economy. I suggest just keeping the dial at 22C, and not on EC mode, if it gets too warm, the air conditioning should come on automaticaly. Also check that the fan is on auto. (W140 drivers can correct me on this because I've never driven a W140)

As for the heated rear seats, I highly doubt you have them on the S280. There would be a switch for them on the rear doorpanels, and wouldn't be controled from the front. When two lights are lit up, it just means rapid heating, on the W126, it turns itself to just one light after a few minutes.

Hi Amo

W126fahrer is 100% correct. EC= economy and the AC compressor turns off to save fuel. The AC is controlled by the climate control system and kicks in whenever your selected temp is exceeded.

w140 AC

I dont know about the 280, but the US version (500)
it is automatic, you set the dials and the system attempst keep that temperature by recirculating and sampling the air going into the little grille by the dome light. When EC is illuminated the compressor is disabled, but all the other functions continue. The heaterd seats are one lamp for low, two lamps fpr high, if you have heated seats in the rear there are identical switches in the arm rest. They time out after while. I never use mine due to the locality, but I pulled the fuse since my dog likes to look out the window and the arm rest is a good place to place your paws.

No, I keep a beach towel on the seat tucked in between the cushions, doesnt' slide around, and keeps him from siding off on hard braking.
